HEATING DEVICE.'

SPECIFICATION forming part of Letters :Patent N o. 672,876, dated April23, 1901. Application filed August 20, 1900. `Serial No. 27,471. (Nomodel.)

To all whom t may concern:

Be it known that I, ARCHIBALD DAVID CAMPBELL, a citizen of the UnitedStates,re siding at Stabler, inthe county of Wilcox and State ofAlabama, have invented a new and useful Heating Device, of which thefollowing is a specification.

This invention relates to heating devices for general use, butparticularly adapted for use as a foot-warmer for vehicles; and theobject of the same is to provide simple, effective, and compact meansfor inclosing a heat-- ing medium which is automatically adjustable tocompensate for variations in position of the vehicle, as in ascending ordescending hills or inclines, and also to make the said heating mediumconveniently accessible for adjustment or removal and to replenish thefuel or combustible material thereof, and, furthermore, to applyconvenient exterior devices for serving as foot-resting means.

The invention consists in the construction and arrangement of theseveral parts, which will be more fully hereinafter described andVclaimed.

In the drawings, Figure 1 is a perspective view of the improved heatingdevice shown in closed condition. Fig. 2 is a similar view of theimproved device shown open. Fig. 3 is a longitudinal vertical section ofthe device in closed condition. Fig. 4 is a transverse vertical sectionof the device on the line 4 4, Fig. 3. p f

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral 1 designates a base, which inv the preferred use of thedevice is secured to the bed of a vehicle close to the dashboard byend-securing clips or clamps 2, which may be of any desired or selectedform adapted for the purpose. On the base an inclosure 3 is mounted andcomprises a lower fixed section 4, including a front rail 5, with anouter convex surface 6 and a movable section 7 hinged to the rear of thesaid fixed section and provided with opposite heads 8, havingsightopenings 9 therein covered by glass panels 10, carried in hingedframes 11, so that in the event of breakage of either of said panelsthey may be readily replaced by new i ones by opening the .frames andapplying them to the inside of the latter. The opening movement of thesection 7 is limited by slotted links 12, one at each end, pivoted attheir lower ends to the rear portions of the ends of the section 4 andhaving the slots ,thereof in engagement with the headed studs 13l on theheads 8. The upper edges of the heads8 are formed in the arcs ofcircles, and connected thereto isa semicyliudrical sheetmetal cover 14,having a front extension 15 to overlap the convex surface 6 of the frontrail 5 of the lower section toform atight joint and exclude drafts ofair, whichmight interfere with the regular combustion operation Yof theheating medium within thedevice. The front vportions of heads 8 are alsocut olf at an upward bevel, as at 16, to coincide with theupwardly-inclined ends 17 of the front rail 5 to avoid the formation ofa straight jointure of the front meeting edges of the two sections, andthereby obstruct the entrance of currents of air therethrough. When thetwo sections are in closed condition, the movable section is held lockedagainst accidental opening by a suitable catch 18, and to facilitatecombustion the center of the cover is provided with a rectangularupstanding ventilator 19, with openings 19a in the sides and endsthereof, and closed at .the upper portion by a flat top 20, extendedheat having egress through the ventilator' from rising directly in avertical manner, and thereby render the device more eective in itsheating action.

At each end of the lower iixed section 4 a receptacle or smallcompartment 22 is provided and has a hinged lid or cover 23. 'Thesecompartments are intended to receive articles pertaining to the heatingmedium, such as wicks and matches or any other devices that may beneeded or found desirable to have within convenient reaching distance ofthe said medium, and the inner opposing walls of the said compartmentsare formed by vertically-extended supports 24 and 25, braced andconnected by opposite longitudinal rails 26, to which and the-saidsupports a semicir- IOO cular shield 27 is secured and depends towardthe base 1. The support 24, as clearly shown by Figs. 2 and 4, is formedwith alower transversely-extending slot 28, with which communication ishad by means of an outletslot 29, comprising a lower vertical leg 30,continuing into an upwardly and forwardly inclined longer leg 31,opening out through a horizontal seat edge 32, provided by the formationof a hinge-section 33, which is normally held closed by a hook 34,movably attached to the upper inner portion of the support 24 to engagea headed stud 35 on the said section. At the inner lower angle of thesect-ion and the adjacent angle of the recess provided in the support 24for the reception of the said section a bearing-seat 36 is provided andforms the center for describing the lower curved slot 2S, and it will beseen that when the section is closed the outlet end of the slot 29 andthe said seat 36 are completely shutolf from exterior communication andthe' parts which engage the same cannot be removed until the saidsection is opened. In the lower portion of the support 25 a slot 37 isformed similar to and in alinement with the slot 28 of the support 24,and above the said slot 37-the supportis also provided with a seat 38 inalinement with the seat 36 and having an upper inclined wall 39 forconvenience in disengaging the part that normally rests therein.

The supports 24 and 25, provided with seats and slots, as set forth,have an elongated cylindrical oil or fuel containing reservoir 40mounted between them, the said reservoir being provided withtrunnion-pins 41 and 42 at each end and upper wick-burners 43. The saidtrunnion-pins movably engage the seats and slots of the said supports,the upper pins 41 serving as pivots to permit the reservoir to swing tocompensate for different angular positions of the entire device andmaintain the burners 43 in upright position and the lower pins 42limiting such movement of the reservoir within the length of the slots28 and 37. The burners 43 are detachable, and though two only are shownit will be understood that the number may be increased proportionatelyto the capacity of the reservoir and the general dimensions of theimproved device, and in decreasing the proportions a single burner willat times be used solely. It is proposed to use lamp-oil, lard-oil, orother suitable like material for fuel, and for convenience in fillingthe reservoir, trimming the wicks, and cleaning the burners the saidreservoir is made removable. To remove the reservoirthe hinge-section 33is first opened outwardly from the support 24 to thus clear the seat 36and the outlet of the slot 29, and by drawing the lower pin 42 on theleft end upwardly through the said slot 29 and correspondingly cantingor tilting the reservoir the pins 41 and 42 at the right end can bewithdrawn from their seat and slot and the reservoir entirely cleared.To reset the reservoir, a reverse operation is pursued, the pins 41 and42 at the right end being first placed in their respective slot 37 andseat 38 and the left pins then disposed in their slot and seat and thesection 33 closed and locked to render it impossible for the reservoirto become displaced or canted while in the warmer in an irregularmanner.

By the movement of the reservoir the burners will always be preserved inproper position relatively to the ventilator with obvious advantages,and as an essential auxiliary to the successful operation and equipmentof the improved device it 'is formed with a front fender 44,comprising-end brackets 45, secured to the base and having front curvedmembers 46, connected by a series of bars 47, which stand in advance ofthe inclosuresections and on which the feet may be rested in warmingproximity to the heating medium. This fender will be preferably formedof steel, though other materials may be used, and in the generalconstruction of the device such composition of metal and other materialsor metal alone of diierent thicknesses will be used, as found bestadapted to serve the purpose and to render the entire device durable,light, and not liable to fire at any portion.

The improved device, as before indicated, is specially adapted for usein all kinds of vehicles as a foot or other warming medium; but it isnot limited to this particular employment, as it is also intended to useit in heating roomscompartments such as pantries and cupboards, asWellas closets-and also in places where articles of food may be storedand liable to be seriously aected by cold temperatures. The severaladaptations may require a modification in the parts, and therefore it isobvious that changes in the form, size, proportions, and minor detailsmay be resorted to without departingfrom the prineiple of the invention.

Having thus described the invention, what is claimed as new is- 1. Inadevice of the character set forth, the combination of an inclosurecomprising a movable and a fixed section, a heating mediumhaving burnerspivotallyand removably mounted in the said fixed section andautomatically operating to maintain the burners uppermost, andsupporting means having a section thereof removable from a remainingportion for permitting a removal of said medium from the inclosure, themovable section of the inclosure being closable over the said' medium.
